This was my first booking on airbnb so I was unsure of the outcome, but in the end it has been one of the best city holidays I had in my life.
The apartment is tiny but perfect for me as I was traveling alone this time.
On Nut (Sukhumvit soi 77) is a fantastic location for living among Thai people unlike the low Sukhumvit sois that have become a frenetic tourist trap. It's full of shops, food stalls, fresh food markets, restaurants. It is also well connected by BTS to other areas of the metropolis. You can reach BTS in about ten minutes walking or, if it's too hot or you're too lazy, a 20 baht 2 minutes ride with motorbike taxi.
Mr K. is the most welcoming of hosts and speaks an excellent English which made communication easy and pleasant. The building is outstanding with high security and a nice view. Everything was just as described and I could not have asked for more. In this part of Bangkok you may find cheaper solutions but not better ones IMHO, and I do hope to come back.
